Koby's cowardice and self-pity have been replaced with confidence and resolve, although he remains polite, self-effacing, and somewhat apologetic or timid if he feels he oversteps in his ambitions or station (such as publicly stating his goal to become a Marine admiral). He continues to be an emotional, compassionate person who can easily be driven to tears for a variety of reasons, which led to Zoro jocularly calling him a "crybaby" during their reunion at Water 7. Much like Luffy, Koby contains and acts with selfless motives and compassion, being devoted to helping people, both civilians and his fellow Marines, unconditionally, which earned him immense popularity. He has run into people at Levely and bonded over shared admiration for the Straw Hat Captain, though Koby has attempted to deflect his own due to his station in the Marines. Smart and quite perceptive, Koby has an eye for spotting small details and the emotions of others. He is also naïve, as he held a firm belief in the blanket integrity of the Marines, only to have it dashed when he witnessed the actions of Axe-Hand Morgan, yet it would strengthen his own resolve to become, in his words, "a real Marine." Initially, Koby was an ordinary boy without any real physical prowess or fighting skills (according to Alvida, his only asset was a measure of navigational knowledge).He gained some fighting skills after he trained under Vice Admiral Monkey D. Garp, alongside Helmeppo, learning the Six Powers, surprising Luffy and Zoro with the amount of growth he'd undergone. Koby reached the rank of Captain, granting him command over lower-ranked Marines and charge of his own ship. In addition to this, at some point he became a member of the covert Marine squadron SWORD, who are granted enough free reign to take on missions normal Marines could not, including challenging any of the Four Emperors. Koby is an extremely skilled Armament Haki user. He is strong enough to shatter Avalo Pizarro's gigantic island hand, which was roughly the size of a mountain. This feat sparked immediate astonishment. Koby has grown thinner and taller, standing close to Luffy in height. He has also gained a cross-shaped scar above his right eye, presumably earned under Garp's heavy-handed tutelage. His hair has grown longer and shaggier since his growth spurt, but it has retained its kobi pink color. Koby wears a standard-issue Marine jacket, pants, and neckerchief as well as a brightly patterned bandanna worn tied across his forehead. Koby's glasses are still present, but he has adopted the habit of wearing them pushed up on his forehead, occasionally using them for reading.
